[✨] Add a "discovering Qwik Community plugins" capability for the Qwik CLI

[shairez]

Is your feature request related to a problem?

We plan to move integrations into their own community plugins repos

So we need to write a capability for the Qwik CLI to be able to discover installed community integration plugins and to use them in the CLI

Describe the solution you'd like

1. A convention for npm packages like qwik-plugin-x
2. A plugin manifest file containing: "title", "description" and relevant files to install.

Describe alternatives you've considered

n/a

We moved this issue to qwik-evolution repo to create a RFC discussion for this.
Here is our Qwik RFC process thanks.
